Olsem wanem long ritim mak bilong yu

  • Raunpela mak: 100% rausim hamas lain bilong yu i bin lusim sirkol i fit gut long em, olsem mak bilong raun bilong dispela sirkol. Sapos lain i suruk liklik 2% long olgeta hap, mak bilong en em 98%.
  • Kala bilong lain bilong yu: grin long hap lain i stap antap long sirkol, na senis i go long yelo, i go inap long ret long hap em i lusim sirkol tru.
  • Sirkol lain i brukbruk: sirkol i fit gut tru long droing bilong yu. Sapos lain bilong yu i pas klostu long en, mak bai i antap moa.
  • Nambawan mak bilong yu: nambawan mak yu kisim long dispela brausa, na em i holim narapela narapela mak bilong taim yu yusim pinga na taim yu yusim maus, long wanem pinga na maus i droim narapela kain tru.
  • Rot bilong droim: raun i go long klok o raun i go long sait narapela. Planti manmeri long US i droim i go long sait narapela; long Japan planti i droim i go long klok [1].

Yu inap droim sirkol i raun gut tru long han?

I no stret olgeta, tasol yu inap kam klostu. Sirkol man i droim long han bai i raun liklik, long wanem han i save go isi na hariap taim em i bihainim kona [2]. Long skel bilong mipela, lain i lusim sirkol bilong em 2% long olgeta hap bai kisim mak 98%. Wanpela tisa bilong matematiks long Kanada i droim sirkol i kamap viral, na wanpela man bilong raitim blog i skelim olsem sirkol bilong en i raun klostu 99.7% [3].

Ol hariap save

  • Rot bilong droim i dipen long ples yu bin bikpela long en: long klostu 50,000 droing bilong US long gem Quick, Draw! bilong Google, 86% bilong ol sirkol i raun i go long sait narapela; long klostu 800 droing bilong Japan, 80% i raun i go long klok [1].
  • Pasin bilong rait i senisim rot: ol pikinini Japan i droim planti moa sirkol i go long klok taim ol i go long skul, na ol pikinini US i droim planti moa i go long sait narapela; ol pikinini Japan i stap long US i droim liklik moa i go long klok [4].
  • Lo bilong spid bilong han: han i go isi moa long ol kona i strong, na hariap moa long ol hap i flat ("lo bilong pawa bilong tupela hap namel"). Long sirkol kona i wankain long olgeta hap, olsem na dispela lo i makim spid bai i wankain [2][5].
  • "Man i winim olgeta long graun": tisa bilong matematiks long vidio sirkol i bin kamap viral, bihain em i tok taitol bilong em olsem "man i winim olgeta long graun long droim sirkol fri long han" em tok pilai em i save tokim ol sumatin bilong em [6].
  • Em i no mak bilong sik: wanpela tingting bilong 1970s olsem droim sirkol i go long klok em mak bilong sik bilong tingting, i no kisim sapot long ol wok painimaut bihain [7].

Olsem wanem tes bilong sirkol i wok

  1. Droim. Putim pinga bilong yu (o presim maus) long wanem hap na droim wanpela sirkol raunim liklik mak, long wanpela pasin tasol.
  2. Lukim taim yu droim. Taim yu raunim hap bilong sirkol pinis, mak bilong raun i kamap namel na kala bilong lain i senis.
  3. Apim. Taim yu pinisim, sirkol i fit gut bai kamap olsem lain i brukbruk, na mak bilong droing bilong yu bai kamap.

Bilong kaunim droing, yu mas raunim inap long 320° o moa, pinis klostu long ples yu bin stat, bikpela inap (radius i mas longpela olsem 15% o moa bilong bikpela bilong ples droing), na pinisim insait long 30 seken. Plis droim wanpela raun tasol. Mipela i fitim sirkol long ol poin bilong yu long rot bilong liklik hevi olgeta, na skelim namba wanwe bilong ol poin long sirkol. Ol sirkol pinga mipela i skelim wantaim ol sirkol pinga tasol.

Bilong wanem i hatwok long droim sirkol i raun gut?

Taim yu droim sirkol, solda, skru bilong han, rus bilong han na ol pinga i mas wok bung, na rot bilong muv i senis olgeta taim. Han bilong yu i save hariapim na pasim spid wantaim kona [2], na olgeta senis bilong spid inap mekim yu lusim rot i go ausait o insait. Long fon, pinga bilong yu tu i haitim lain yu wok long droim. Maus i muv wantaim olgeta han, olsem na mak bilong sirkol maus na sirkol pinga i no wankain.

Samting bilong helpim sirkol i raun gut moa

  • Droim bikpela moa na yusim olgeta han. Ol liklik sirkol pinga tasol i save raun liklik moa.
  • Holim wankain spid. No ken isi tumas: droim isi tru i save mekim han guria.
  • Lukluk long liklik mak namel, i no long lain. Wok bilong yu em long holim wankain longwe long namel.
  • Pinisim raun isi na gut. Planti sirkol i lusim mak long pinis, taim man i hariap long kamap long ples em i bin stat.

Dispela tes inap tokim yu long wanem samting, na wanem samting em i no inap tokim yu

Tes bilong sirkol em pilai bilong traim bosim han. Mak bilong yu i dipen long divais bilong yu, sais bilong skrin, yu yusim pinga, pensil o maus, na hamas yu bin traim pinis. Em i no tes bilong sik o tes bilong han guria; dokta i yusim ol narapela wok bilong droim, olsem droim spiral, bilong dispela [8]. Rot yu droim sirkol i no tokim wanpela samting long helt bilong yu.

Ol askim ol man i save askim planti taim

I gat rot long droim sirkol i raun gut tru long han?

I no gat sirkol man i droim long han i raun gut olgeta, tasol ol man inap kam klostu. Long tes bilong sirkol Helibrain, raunpela mak em 100% rausim raun liklik bilong lain bilong yu long olgeta hap, olsem na lain i lusim rot bilong em 2% long olgeta hap bai kisim mak 98%. Bilong kisim 100% stret, lain i no ken raun liklik liklik tru.

Planti man i droim sirkol i go long klok o i go long narapela sait?

Em i dipen long ples yu bin bikpela long en. Long ol droing bilong Quick, Draw! bilong Google, 86% bilong klostu 50,000 sirkol bilong US i raun i go long narapela sait, tasol 80% bilong klostu 800 sirkol bilong Japan i raun i go long klok [1]. Pasin bilong rait i luk olsem em i bikpela samting moa winim wanem han yu yusim [4].

Olsem wanem yupela i kaunim raunpela mak bilong mi?

Tes bilong sirkol Helibrain i fitim sirkol i nambawan long olgeta poin bilong lain bilong yu (fit long rot bilong liklik hevi olgeta), na bihain i skelim longwe bilong olgeta poin long dispela sirkol. Longwe bilong olgeta poin wantaim, olsem hap bilong radius bilong sirkol, em raun liklik bilong lain bilong yu; raunpela mak em 100% rausim dispela raun liklik. Sapos droing i oval, gat liklik hul, o lain i brukim narapela, mak bai i go daun.

Bilong wanem mak bilong mi i narakain long fon na komputa?

Pinga na maus i yusim narapela ol musel na muv, na skrin bilong fon i liklik moa. Olsem na tes bilong sirkol Helibrain i holim narapela mak bilong yu long taim yu tatsim na taim yu yusim maus, na skelim ol risal insait long wankain kain maus tasol.

Olsem wanem yu inap droim sirkol i raun gut tru taim yu no gat kompas?

Putim han bilong yu i stap strong long senta, yusim liklik pinga o rus bilong han olsem pos, na tanim pepa o han bilong yu raunim. Taim yu droim fri long han, droim ol bikpela sirkol wantaim olgeta han na holim wankain spid. Trening long tes na lukim ol kala bilong lain bilong yu bilong save long wanem hap yu lusim rot.

Tes bilong sirkol Helibrain i fri tru?

Yes. Tes na olgeta risal bilong yu i fri: yu no nid long rejista, salim imel o baim. Helibrain i kisim mani long app bilong en, we i gat fri plen na ol plen yu baim; yu no nidim app bilong mekim tes.

How this test works

This game tests how steady and even your hand is. Put your finger or the mouse button down and draw one circle around the dot in a single stroke. When you lift, we fit the best circle to your line and measure how far your line strays from it, on average. Your roundness score is 100% minus that average wobble, so a line that wobbles by 2% scores 98%. Motor-control labs have measured hand-drawn curves like this since the 1980s.
